FIELD OF THE INVENTION

The present invention generally relates to a random orbital sander. Morespecifically, the present invention relates to a sanding tool attachmentto a random orbital sander in order to sand a plurality of surfacessimultaneously.

BACKGROUND OF THE INVENTION

A sander is a power tool used to smooth surfaces by abrasion withsandpaper. Sanders have a means to attach the sandpaper and a mechanismto move it rapidly contained within a housing with means to hand-hold itor fix it to a workbench. There are many different types of sanders fordifferent purposes. Multi-purpose power tools and electric drills mayhave sander attachments. Often times, user may only need to sand asingle surface which can be done efficiently with electric sanding toolssuch as random orbital sanders. Current random orbital sanders can beused for a multitude of errands from polishing a car to grinding a wall.However, there are instances where a user can sand down multiplesurfaces that are near each other at once (ex; an edge grain and a facegrain of adjacently positioned clapboards). This opportunity can cutdown on work time significantly. Current sanders do not provide asolution for grinding orthogonal surfaces simultaneously though thetools are capable of doing so.

An objective of the present design is to provide the user with a sandingtool attachment that may be attached to a random orbital sander. Thesanding tool attachment provides the user with a tool fastening featureso that the present invention can be attached to a random orbitalsander. The sanding tool attachment also provides the user with twoother fastening features so that the present invention can secure around sanding pad and a rectangular sanding strip. More specifically,the round sanding pad, the rectangular sanding strip, and the sandingtool attachment create a pair of functional surfaces that allow the userto sand orthogonal surfaces simultaneously.

All illustrations of the drawings are for the purpose of describingselected versions of the present invention and are not intended to limitthe scope of the present invention.

The present invention is a sanding tool attachment that is utilizedwithin a random orbital sander to sand a plurality of surfacessimultaneously. More specifically, the present invention enables theuser to attain a flat sanding surface and a lateral sanding surface sothat orthogonal surfaces can be simultaneously sanded. For example, thepresent invention can be utilized to simultaneously sand an edge gainsurface of an arbitrary clapboard and a face grain surface of adjacentclapboard. In reference to FIG. 1-4, the present invention comprises anannular attachment body 1, a plurality of dust extraction holes 6, atool fastening feature 7, a primary hook fastener feature 8, and asecondary fastener feature 9.

In reference to FIG. 1-2, the annular attachment body 1 is a platformthat attaches to a sanding pad of the random orbital sander. The annularattachment body 1 may be constructed of a sturdy and semi-rigid materialsuch a hard rubber so that the annular attachment body 1 is able tofunction similar to the sanding pad of the random orbital sander. Theheight of the annular attachment body 1 is determined upon manufacturerequirements and industry standards to optimize the potential sandingprojects. For example, the height of the annular attachment body 1 canbe ⅜ of inches to precisely match with the standard ⅜ inches thicknessof a clapboard. The

In reference to FIG. 1, the annular attachment body 1 comprises a firstbase wall 2, a second base wall 3, a lateral wall 4, and a central axis5. The first base wall 2 and the second base wall 3 are oppositelypositioned of each other about the lateral wall 4 thus delineating acylindrical shape. The first base wall 2 is concentrically positioned tothe second base wall 3, wherein the first base wall 2 is perpendicularlypositioned to the lateral wall 4, and the second base wall 3 isperpendicularly positioned to the lateral wall 4.

In reference to FIG. 3, the first base wall 2 is perimetricallyconnected to the lateral wall 4 so that the tool fastening feature 7 isable to integrate onto the first base wall 2. In other words, the toolfastening feature 7 attaches the first base wall 2 to the sanding pad ofthe random orbital sander. Preferably, the tool fastening feature 7 is aloop fastening feature to accommodate an existing hook fastener systemthat is premanufactured into the sanding pad of majority of the randomorbital sanders. However, the tool fastening feature 7 can also be ascrew fastener, peal and stick type adhesive fastener, or any other typeof fastener that enables the mounting of the annular attachment body 1.

In reference to FIG. 4, the second base wall 3 is perimetricallyconnected to the lateral wall 4 so that the primary hook fastenerfeature 8 can be integrated onto the second base wall 3. In other words,the primary hook fastener feature 8 enables the existing round-sandpaperto be attached to the annular attachment body 1 through apremanufactured loop fastener system of the existing round-sandpaper. Asa result, the present invention provides the flat sanding surfacethrough the second base wall 3 so that the user can use the existinground-sandpaper to sand a primary flat surface.

Furthermore, a diameter of the first base wall 2 is equal to a diameterof the second base wall 3 thus ensuring the precise alignment of theannular attachment body 1 in between the sanding pad of the randomorbital sander and the existing round-sandpaper.

In reference to FIG. 2, the plurality of dust extraction holes 6 isradially distributed around the central axis 5 and traverses from thefirst base wall 2 to the second base wall 3. Furthermore, each of theplurality of dust extraction holes 6 is oriented perpendicular to thefirst base wall 2 and the second base wall 3. Due to the positioning ofthe plurality of dust extraction holes 6, the present invention is ableto maintain functionality of the dust collection system that isgenerally premanufactured into the random orbital sander. For example,the plurality of dust extraction holes 6 are able to extract majority ofthe dust particle that are created during a sanding process and redirectthem away from the sanding surface.

In reference to FIG. 3-4, the secondary fastener feature 9 beingintegrated onto the lateral wall 4. Preferably, the secondary fastenerfeature 9 is a secondary hook fastening feature to accommodate apremanufactured loop fastener system that is into the existingsandpaper. More specifically, the user can attach a premanufactured loopfastener system of a rectangular sanding strip to the lateral wall 4through the secondary hook fastening feature. The rectangular sandingstrip can be measured and cut from standard sandpaper sheets or can bemanufactured to exact height of the annular attachment body 1. In otherwords, the present invention provides the lateral sanding surfacethrough the lateral wall 4 so that the user can use the rectangularsanding strip to sand a secondary flat surface that is orthogonal to theprimary flat surface. However, the present invention can also bemanufactured without the secondary fastener feature 9 to accommodate apeal and stick type adhesive fastener that is also premanufactured intosome of the sandpaper.
